TSC Puralloy® SN100C is a lead-free solder alloy, comprised of tin/copper. TSC Puralloy® SN100C is a cost-effective, lead-free solder alloy developed and patented by Nihon Superior Co. Ltd in Japan. SN100C has been manufactured using a tin/copper eutectic alloy, with the addition of small quantities of
both Nickel & Geranium. The inclusion of Nickel reduces copper dissolution and creates shiny joints, the addition of Geranium reduces dross production. These additions ensure that SN100C is a suitable alternative for any lead-free wave soldering process with comparable performance to SAC alloys, with a lower cost of ownership that SAC alloys.
